Suggest me a book where an estranged family member returns to someone’s life. Preferably a father returns, so he’s been there before, it’s not a first meeting

This is basically what's Happening in my life and I'm having a really hard time processing this. I'm hurt, angry, emotional and even though my fiancé is supportive of me he doesn't have a frame of reference to really understand. I grew up for a couple years with my parents, so it's not like this guy is a complete stranger. I knew my dad growing up, and we wrote letters after the divorce. In high school he started becoming angry during every phone call. He didn't attend my graduation or offer congratulations. It's as though after I grew up as a legal adult he dropped off the face of the planet

Now he's reached out, 13 years later. I don't need anything from him and am wary of starting a relationship. I'm emotional but
can't say why other than that this all feels weird. I don't hate him but also don't feel any liking or a connection. I might look into therapy but it would be hard to budget that in.

So in the meantime, I'm trying to find a book that might help. Thank you for reading this
